Up to 25,000 Penelec customers in the Erie region lost power following an equipment failure at a substation in the city this morning, company spokesman Bill Jerin said.

Less than 1,000 Penelec customers remain without power following an equipment malfunction at Penelec's Erie South substation, at West 26th and Poplar streets. Crews are working to fix the problem, and all customers should have their service restored within the next half-hour, Jerin said.
